My sister sneaks into my futon every night and approaches me... If I let my guard down, she takes off my pants right away! She kicks down the door and comes into the bathroom, toilet, and even my room while I'm masturbating (crying). My dick doesn't have time to rest when living with my sister who loves her brother! "My sister comes into my futon without permission." "My sister comes into the bath without permission." "It's no use to lock the door in front of my sister." "My sister even comes into the bathroom." "My sister is jealous of my girlfriend."
